There is a new AR-15 free float hand guard on the market. The MPR, or Multi Purpose Rail, from V7 Weapon Systems is now available.
The MPR is fairly lightweight at 12.6 ounces (15.2 with the barrel nut) for a 13.5″ rail, as you would expect from V7 Weapon Systems. They managed to keep the weight to a minimum by aggressively removing material from the rail everywhere they could. This includes machining grooves into the full length top rail and short, forward 3, 6, and 9 o’clock rails. The MPR also features 4 QD sling swivel sockets (1 forward and 1 rear on each side).
The included barrel nut might merit a post of its own. It is designed to make timing the nut as easy as possible. It lacks teeth so you don’t have to line up a pass-through for the gas tube and it features 32 different mounting positions so you can set the torque where you want it. On top of all that, you don’t need a specific wrench to install it. It can be tightened with a 1″ or 1 1/8″ wrench.
You can check out the MPR at V7 Weapon Systems.
